Honfleur is a city in the department of Calvados, in northern France's Normandy region. It's on the estuary where the Seine river meets the English Channel. The Vieux-Bassin (old harbor), lined with 16th- to 18th-century townhouses, has been a subject for artists including Claude Monet and native son Eugène Boudin. Nearby is 15th-century St. Catherine's Church, a vaulted timber structure erected by shipbuilders.
